    Interesting that the rifle shoot well. Does it fowl quickly?

    Also the mirrors on the bore scopes are fragile. I wouldn't put mine through a dirty bore, only clean dry bores for mine.

    Thank you -that was quite interesting.


    I have a .240 Weatherby barrel that looks like the first photo.

    They "forgot" to ream it after drilling .......
    But then they hammer forged it.

    Strangely enough it shoots but for how long?

    I don't mind MAX loads in this barrel.

    In my experience your pictures are pretty much typical for Savage Barrels. I've seen some better and some worse.

    Picture of one of the better ones - the throat of my 112BVSS in 7mmMAG after 30 rounds:



    The same rifle's factory crown looked like this:



    After I recrowned it, it looked like this:



    One of the worse ones - the throat of a new never fired Savage 10PC in .308:



    One of the much worse, small part of a 6" section of the barrel that used to be on my Savage Model 10 .243:



    Spend a few hours with a bore scope looking at all the new rifles you can find will probably revise your estimate of factory bore quality downward quite a bit. It did for me at least.

    This is my home made adaptor for taking pictures of bores with my buddies Hawleye and my Nikon 990:



    I mount the camera on a sled and the barrel in wooden ''V" blocks to be sure the camera never has to be held up by the very fragile borescope.

    Ron,

    It does foul up quickly and I suspect so does the accuracy. I wish I had this borescope earlier.

    You are welcome. This is the "sled":



    It's pretty crude but it works great.

    I have a number of wooden v-blocks that fit in the wood frame to be able to level a barrel, or barreled action, so the borescope can slide into it. The fact that the Nikon 990 has a preview screen that can be rotated to point up when the lens is horizontal was a big help. I sometimes hook it to a computer monitor if there are other folks who need to see the bore in real time.

    I have tried to take pictures from my borescope with not much success, Do you have to run the camera in a manual mode and adjust the shudder speed fore a longer exposhure?
    Thanks in advance for any info.

    I think that is why barrel makers like for the shooters to have bore scopes. It sells a lot of barrels.

    I use the zoom to make the picture bigger, I use auto focus but some times I have to focus the borescope to get into a range where the autofocus will work. I leave the exposure on automatic. The 990 has a best picture mode that takes 10 exposures and saves the sharpest image. I use that feature but I don't think it's really necessary.

    I'm not doing anything special - it just works. I sometimes with I had a brighter light but I get good enough pictures with what it came with.

    You could be right, but I think, truth be told, I've used the borescope combined with slugging to rule out barrels as the problem more than to confirm it. There can be a lot of reasons a rifle doesn't shoot well - the throat, crown, and bore are just three of them. Crowns are usually a simple fix. Gross problems, like the ones I posted pictures of, throats that look like a dry lake bed from being shot out (which can be done in a remarkably small number of rounds if the barrel isn't allowed to cool - like matches where people shoot 15 rounds in 6 minutes over and over), are difficult to diagnose with certainty with out a scope - easy with a scope.

    The most common problems I've seen on hunting rifles are bedding issues (including barrels touching) and scope mounts. The next most common - cleaning rod damage, triggers, scopes.

    I've also seen barrels with almost no rifling in them. I have one in the shop now. I "need" to take a picture of that one. It's almost a smoothbore on one side of the barrel from throat to crown. My buddy says it never shot right, bullets go thorugh the paper sideways at 50 yards. And it's a .22 Hornet.

    The borescope is just another inspection tool. It does't fix anything. Expensive, rather specialized, but still just a tool for looking where it's hard to see.

    Actually Butch, it might be the other way around. Most people don't have a clue as to what they are looking at - and even if they do, does it really affect the performance of the barrel?

    The bottom line is, "how does it shoot?"

    In my experience a borescope is mandatory for doing a competition 22lr rimfire chamber.
